INSPECTION AND ADJUSTMENT OF BRAKE FREE PLAY
INSPECTION:
(Brake lever free play must be checked with the engine shut off.)
Brake lever free play for front and rear wheels
When checking the hand-braking lever for front
and rear wheels, its free play (the stroke of
hand-braking lever from no braking to initial
braking) should be 10~20mm.
It is abnormal if the feel is spongy when holding
the hand-braking lever forcefully.
Adjustment:
The indentation of brake adjustment nut must
be aligned with the pin. (see right figure)
CAUTION:
When free play is between 10~20 mm, check
brake indicators of front and rear wheels. If
the arrow on the brake arm aligned with the
“
△
” marked on the brake disk, that means
the brake lining has been excessively worn,
and must be replaced immediately.
Turn the adjustment nut on brake arm of front and rear wheels to adjust the free play of hand-brake
lever.
Hold the hand-brake levers after adjusting with both hands until there is effective brake feeling.
Measure the free play with a rule.
